4Subject: [PATCH] cgroupfs: create /sys/fs/cgroup to mount cgroupfs on
5
6We really shouldn't be asking userspace to create new root filesystems.
7So follow along with all of the other in-kernel filesystems, and provide
8a mount point in sysfs.
9
10For cgroupfs, this should be in /sys/fs/cgroup/ This change provides
11that mount point when the cgroup filesystem is registered in the kernel.
